Just installed and enabled root for apps and adb, but root is broke. I can't get titanium to work as it can't get root permissions. Joey Kim's root checker says its not, and if I keep checking it then says it is, but can't get root in titanium. This was a very clean install. Any ideas?

You can regain root through recovery. In philz recovery, under philz options, there is a re root. Then just download SuperSU from the play store. If you have a different recovery, just flash whatever root.zip you flashed to get root in the first place.

How good is this to use with CyanogenMod? I use LiquidSmooth+Quantum Kernel (AT&T Version) and wasn't impressed, maybe because of the ROM. I'm back on CyanogenMod with no custom kernel, is it worth it?

YMMV. Currently using Quantum ROM with the latest Quantum kernel (Sprint version) and getting the highest AnTuTu score of any ROM I've tried. If the ROM had a theme engine I'd call it perfect!

anyone getting force closes, mostly of Google plus when I open any app. Also getting random reboots, multiple times per day. This was a very clean install.

Nav Bar

I have the navigation bar disabled but every time I turn my phone on the navigation bar is there until I go to settings/navigation/navigation bar and click to enable and then click again to disable in order for it to go away. Otherwise awesome rom and kernel. Any ideas would be greatly appreciated! ;)

Disable the xposed. There's a fix in the att forums for it.

Anyone else stuck on ROM boot animation?

Nevermind - the ZIPs were not good. Re-downloaded and now all is well.

Is there a plan on when the next build is going to be dropped? This 4.6-based build is having some LTE issues (I am on Ting - a Sprint MVNO) :(

Thanks for the ROM, dev. Appreciate your hard work!

Edit, nevermind. Remounted sd seemed to fix it.

Please delete this post.

I'm having issues with the gallery not showing my sd card pictures. All other apps seem to read my card fine, but the gallery doesn't show them at all. Any ideas?

Frequent random reboots without touching anything. Anyone else experiencing this? Happened twice trying to make phone calls

    It's all d2lte but there's also some fixes in there to make sprint LTE work. Enjoy it!

    Is there a way to kill recent apps in one fell swoop?

    Sent from my SPH-L710
    Since this is based on SlimKat I'm going to assume it uses Slim's recent apps. Finger and thumb at top and bottom, pinch together

    Check the att threads, they get updated more often. I've been busier lately so you can even just go and check the dev host folder!
